I think up to here their obvious candidates to put into scsi-misc ASAP
once we can get an ACK from Achim.

I think we want to put this in, but maybe keep the modular paramter for
now and print a big warning if anyone actually specifies it.
Achim, do you have any opinion on this?

Sure, feel free to add it.

As I mentioned in my reply to the patch I'd prefer to just use dev_id
directly like any modern driver.

if you use pci_get_device you need to call pci_put device to drop a reference
when you're done with the device (or in a failure path).

Looks good. But we'll need some proper locking for this list once we
start supporting pci hotplug.

I'll look at these four patches later on, I'm a bit too tired to follow
it right now, sorry.
Thanks a lot again for doing all the work on this driver!
